Topic tags/keywords: plywood butt joint dowel joint router joint joining

I’m an artist and am working on some shaped canvases using plywood forms for the stretchers. I want to avoid wastage and cut out the forms in parts rather than use up a single sheet. I made one so far cut in two long pieces and joined using dowels with a butt joint, but I’m wondering if I could make that stronger. I rout the adjoining edges so they match so I could easily (I think) cut a short scarf joint with an angle bit or even cut some sort of finger or puzzle joint along with the dowels. There will be a steel strap on one side to keep it straight.

Do I need to bother making the joint more complicated or is a doweled butt joint fine? Any advice?

This is an example of what I’m doing (ignore the branch). This was cut from 3/4” plywood in two long pieces app. 48” lomg and joined on the short sides. Thanks for any help.
George

if one side is not to be exposed to the view corrugated fasteners would be perfect !

Dowels are fine.
